By condensing monohydroxy tetraphenylene derivatives with p-phenylene di-isothiocyanate, Bis-TPE was produced. A fluorescence spectrophotometer was used to scan the fluorescence emission spectra from 380 to 700 nm with 360 nm as the excitation wavelength. The fluorescence spectra showed that Bis-TPE exhibited high selective sensing ability for lutein in aqueous medium, and the fluorescence showed red-shift phenomenon with a limit of detection as low as 0.26 μM for lutein. The sensing mechanism was confirmed by mass spectrometry, infrared, and fluorescence Job's plots based on the 1:1 stoichiometric ratio of double hydrogen bonding. The successful application of Bis-TPE in sensing test strips means that Bis-TPE can achieve efficient detection of lutein in complex environments. As a result, an aggregation-induced luminescence-based lutein fluorescence sensor was constructed, which exhibited highly selective and sensitive sensing of lutein, and provided a new research idea for the object detection of such structures.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 9","pages":"1111-1120"},"PeriodicalIF":1.6,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141501308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This metal chalcogenide expressed a tuned band gap of 3.84 eV and an average crystallite size of 20.52 nm. Functional groups explored for BaLa2MnS5 expressed strong signals for presence of the metal sulfide bonds. The thermal decomposition pattern of BaLa2MnS5 followed a two-phased mechanism. Synthesized metal sulfide possessed an irregular morphology with particles arranged in random manner. An assessment of the chalcogenide BaLa2MnS5 for energy applications has been carried out. When employed as an electrode material in 1 M KOH, which acted as the background electrolyte, BaLa2MnS5 chalcogenide showed a specific capacitance of 597 F g−1. Furthermore, this BaLa2MnS5 chalcogenide decorated electrode has a low resistance, as shown by the Rs of 1.35 Ω, and a specific power density of 7366 W kg−1, according to the impedance investigations. The electrochemical results for the OER activity are indicative of the OER overpotential and Tafel slope values as 388 mV and 108 mV/dec. This electrode achieved the HER overpotential value of 241 mV while the obtained Tafel slope was 194 mV/dec.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 9","pages":"1008-1020"},"PeriodicalIF":1.6,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141528826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our simulations, resulting from variations in geometry and vertical excitation charge reorganization, unveil solvent polarity-dependent hydrogen bonding interactions and charge recombination induced by photoexcitation that can significantly enhance the excited state intramolecular proton transfer (ESIPT) reaction for TPHY chemosensor. By constructing potential energy surfaces (PESs), we reveal that the single ESIPT reaction of TPHY occurs concurrently with alternative dual intramolecular hydrogen bonds (O1-H2···N3 and O4-H5···N6). We sincerely hope that the regulation of solvent polarity on excited state behaviors may pave the way for the development of innovative luminescent materials.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 9","pages":"1036-1044"},"PeriodicalIF":1.6,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The N,P-CDs were prepared using arginine as carbon and nitrogen sources according to hydrothermal method with favorable luminescence intensity, photostability, and good reproducibility. And the N,P-CDs were used as internal reference fluorescence molecules. The anionic Eosin Y was used as fluorescence signal molecule. Protamine with positive group could interact with Eosin Y through electrostatic effect, leading to the fluorescence quenching of Eosin Y. Upon the addition of heparin, heparin was combined with protamine with stronger affinity through electrostatic interactions and hydrogen bonds, which preventing the bonding of protamine with Eosin Y and obvious fluorescence emissions of Eosin Y at 538 nm could be observed. Meanwhile, the fluorescence signal of N,P-CDs at 420 nm remained stable during the whole process. A good linear range between the fluorescence emission intensity ratio of I538/I420 was obtained for protamine from 0.01 to 40 μg/mL with a low detection limit of 5.6 ng/mL, and heparin from 0 to 35 μg/mL with a low detection limit of 2.5 ng/mL. Moreover, the method was further applied to detection of heparin with satisfactory results in fetal bovine serum samples.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 9","pages":"1084-1091"},"PeriodicalIF":1.6,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the challenge in biological samples is the variability in relative concentrations (0.1%) of site-specific tyrosine phosphorylation on proteins. To navigate these fluctuations and accurately quantify the absolute levels of tyrosine phosphosites among different samples, we reported a hybrid data-independent acquisition-parallel reaction monitoring (DIA-PRM) MS technique for the robust identification and quantification of the phosphoproteome, the establishment of a comprehensive library of tyrosine phosphosites, and the specific assessment of changes in tyrosine phosphorylation. In our model study on non-small cell lung cancer cells, our PRM strategy accomplished by a spiked-in synthetic heavy phosphopeptide demonstrated reliable targeted quantification of the pY1197 on EGFR, revealing levels of 2.5, 4.9, and 5.3 fmol in pervanadate (PV)-treated cells at 0, 15, and 30 min, respectively. Additionally, DIA-extensive phosphoproteomic analysis provided 2765 tyrosine phosphosites within 14,961 global phosphosites corresponding to 1536 phosphoproteins, contributing to the phospho-library establishment and relative quantification of phosphorylation level, especially in the PV-treated time-dependent increase of ErbB signaling pathway. This hybrid DIA-PRM approach will advance the application of precise measurement of changes in multiple phosphotyrosine residues and enhance our understanding of phosphoproteomic dynamics in drug-resistant cascades.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"71 8","pages":"897-907"},"PeriodicalIF":1.6,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
